Constructive Notice to Patent Owner [R-08.2012]

In some instances, it may not be
possible to deliver mail to the patent owner because no current address is available. If
all efforts to correspond with the patent owner fail, the reexamination proceeding will
proceed without actual notice to the patent owner. The publication in the Official Gazette of (A) the notice of the filing of a request
for reexamination, or (B) the notice of the ordering of reexamination at the initiative of
the Director of the Office, will serve as constructive notice to the patent owner in such
an instance.
